noticed he has these white patches on his scales i describe them as looking like someone spilt bleach on him,,the white patches arent fuzzy or raised i netted him to get a really good look.i currently have him in a hospital tank with bacteria/fungal meds applied with a bit of aquarium salt.he seems coherant but just sluggish and breathing hard,was in a 125 gallon and moved to a 100 gallon was with other fish that are fine,water is fine,just cant find any info on what this is
